Effects of satsuma dwarf virus infection on medium-late-maturing citrus ‘Setoka’, ‘Tamami’ and ‘Harumi’

Abstract

Satsuma dwarf virus (SDV) causes serious damage to citrus production, reducing fruit quality and yield. In this study of the effect of SDV infection on growth of 2-year-old pot-grown trees of Satsuma mandarin (Citrus unshiu) and citrus hybrids ‘Setoka’, ‘Tamami’, and ‘Harumi’, SDV-infected trees of Satsuma mandarin, ‘Tamami’, and ‘Setoka’ had altered leaf shapes, shorter leaves and tree forms than did virus-free trees, but these traits did not differ significantly between SDV-infected and SDV-free trees of ‘Harumi’.
